But viewers would have noticed some differences to the character after the dramatic fallout of Season 1.

Now actor Tobias Menzies has opened up about how Randall is a "less confident man" following the injury he sustained in the dramatic finale and due to the unfamiliar setting of Paris.

He told Parade: “I was keen for him to be less confident in the second season, so we see the fallout from the injury he sustained, and the fact that he’s out of his comfort zone. He’s in another country; in a country that Britain is at war with. He’s not in control. So, yeah, he’s less robust, a less confident man in the second season.”
